CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to U.S. Provisional Patent Application No. 62/560,772, entitled: Hinge, filed on Sep. 20, 2017, the content of which is incorporated herein by reference.

TECHNOLOGICAL FIELD

The present subject matter is directed generally to a hinge assembly, and more precisely to a hinge assembly for pivotally coupling opposing portions of a carryable case, especially a case for housing electronics, and adapted as a conduit for electrical conductors.

BACKGROUND

Various forms of electronics-oriented equipment are often housed in a carryable hard-sided case similar to a suitcase, briefcase, or the like, affording convenient portability, security, and other benefits. Frequently, electrical connections comprising wires or cables are permanently extended from one of the opposing portions of the case to the other in order to link electronic components. In such instances, the cables need protection from snarling, stretching, unnecessary flexing and bending, and other mechanical forces that might otherwise damage the wires, especially as a result of repeated opening and closure of the case.

The hinge mechanism coupling the halves of a case would appear to be an expedient means of conveying such interconnecting electrical conductors. Additionally, such a hinge should be sturdy and reliable, as well as easily and inexpensively fabricated and assembled.

Accordingly, it would be desirable for a case enclosing electronic components to have a durable hinge pivotally joining the opposing halves of the case, and adapted to function as a conduit to carry electric cables from one case member to the other, such that the cables are protected from mechanical forces, as well as moisture and debris which might damage the wires. Additionally, the hinge would have a minimum of simple, easily fabricated components, and be readily assembled.

The foregoing background discussion is intended solely to aid the reader and not to limit the innovations described herein. Thus, the foregoing discussion should not be taken to indicate that any particular element of a prior system is unsuitable for use with the innovations described herein, nor is it intended to indicate that any element is essential in implementing the innovations described herein. The implementations and application of the innovations described herein are defined by the appended claims.

DETAILED DESCRIPTION

So that the implementations presented herein may be readily understood, certain terms are first defined. It should be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. It should also be noted that the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise.

In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific implementations in accordance with the described implementations. Although these implementations are described in sufficient detail to enable one skilled in the art to practice the described implementations, it is understood that these examples are not limiting, such that other implementations may be used and changes may be made without departing from the spirit and scope of the described implementations.

Referring to the drawings wherein the present disclosure is directed to a hinge assembly adapted for pivotaby joining the opposing halves of a case, specifically for a carryable case housing electronic apparatus. In FIGS. 1-6 is shown a hinge assembly 10, according to an implementation, depicting its external features in relation to an illustrative case 15. According to the present inventive concept, in FIGS. 1-2 is shown, an example implementation of a hinge assembly 10 connecting the two opposing members of an illustrative case 15 with the opposing case members in an open configuration. In general aspect, the hinge assembly 10 takes the form of an elongated cylinder comprising, in this particular construction, two (2) hinge segments 17 which are attached to opposite halves of the case 15 and rotate about a common axis. In this implementation, the terminal ends 25 of the hinge assembly 10 are closed with suitable caps 30. In some implementations, the caps 30 may provide a seal against moisture and debris from entering the hinge assembly interior, and also protect the terminal ends 25 of the hinge from impact damage.

For illustrative purposes, several representative electric cables 35 are depicted exiting the hinge assembly side wall into the case housing interior 20. In this particular example, the cables 35 exit the hinge assembly side wall near the terminal ends 25. In other possible implementations, the cables may exit the side wall at other locations.

In FIGS. 3-6 the example hinge assembly is further shown in relation to an illustrative carrying case. In FIG. 3 is shown the hinge assembly 10, in end view, joining the members of a case, wherein the case is in an open position. It will be noted that the hinge assembly 10 is mounted to the case housing such that the hinge assembly 10 is disposed substantially between the opposing halves of the case. In FIG. 4 is again shown the hinge assembly 10, in end view, joining the members of a case, wherein the case is in a closed position. It is noted that, when the case is closed, the hinge assembly 10 projects from the case housing. In an implementation, the hinge assembly 10 may be protected from impact by providing suitable corner protectors 45 (see FIG. 5) on the case housing, whereby the corner protectors 45 contact any impinging surface, rather than the hinge assembly 10 itself.

In FIG. 5 is shown the hinge assembly 10, in an elevated view, in relation to an illustrative case, wherein the case is in a closed configuration. In FIG. 6 is shown the hinge assembly 10, in side view, in relation to a closed case. In this example implementation, it will be noted that the hinge assembly 10 does not extend to the ends of the representative case. Such an implementation serves to protect the hinge assembly 10 from damaging impact to the hinge assembly ends. In an alternative implementation, the hinge assembly 10 can extend the full length of the case if desired. As discussed supra, corner protectors 45 applied to the case housing might aid in shielding the hinge assembly ends, as well as other hinge assembly surfaces from unwanted impact.

Moving now to the construction, assembly, and operation of the disclosed hinge assembly according to the present inventive concept, in FIG. 7 is shown a hinge segment 17 attached to a case housing, wherein the hinge segment 17 is divided in half longitudinally, producing two opposing semi-cylinders 50 with a semi-circular cross-section, joined by a pivotable living hinge 60. In order to produce the hinge segment 17, the opposing semi-cylinder portions 50 are pivoted together, thereby forming a hollow cylinder. This operation is depicted in FIGS. 8A-8B. In an implementation, the opposing portions 50 of the hinge segment 17 may be equipped with means for securing the two halves together, such as fasteners included during the injection molding process allowing the portions to be quickly and releasably engaged. Such openable members permit any electrical conductors contained therein to be accessed and serviced if necessary. In FIG. 7 is shown an example implementation of such fasteners 53. In the implementation presented, the ends of the hinge segments proximate to the end panels of the case housing are closed off integrally with terminal transverse walls 63 (see FIGS. 7-9). In some implementations, this closure can be the location of fastening means to hold the hinge segment semi-cylinders 50 together, and may also further impede water and debris from entering the hinge interior. In an implementation, the hinge segment 17 may be integrally affixed to the case housing along the long dimension edge of the hinge segment 17. This may be achieved by plastic injection molding of the case housing with the hinge segment 17 as a unitary component. The hinge segment side wall 40 may also incorporate one or more openings to permit passage of electrical cables therethrough. In an implementation, the hinge segment side wall 40 proximate the case housing may include an integrally molded support buttress 67 (see FIG. 8A) to add additional structural reinforcement to the joint between the hinge segment 17 and the case housing (see FIGS. 3-4, 8A, and 8B). This support buttress 67 may be the location of openings therethrough for cable passage between the hinge assembly 17 and the case housing interior 20.

At least two (2) hinge segments 17 may be combined to form the hinge barrel 65. In some implementations, a multiplicity of hinge segments may be used. In FIG. 13, as an example, three (3) hinge segments 17 are used to comprise the hinge barrel. In the example presented herein, two (2) hinge segments 17, each affixed to opposing case members, are united to form the hinge barrel. In FIG. 9 is shown opposite case members brought together such that their hinge segments 17 are aligned in a mutual axis to form a central hinge channel 70.

After the hinge segments 17 are properly aligned, the hinge barrel 65 produced thereby is secured by a tubular hinge connecting rod 75 (see FIG. 11) which is smaller in outside diameter than the inside diameter of the central hinge channel 70, but of a diameter to fit snugly inside the hinge channel 70. The hinge connecting rod 75 is formed in substantially the same manner as the hinge segments 17. In FIG. 10 is shown an example hinge connecting rod 75 comprised of two (2) opposing semi-cylinder portions 80 coupled by a living hinge 61. As depicted, the semi-cylinder portions 80 define hinge connecting rod side walls 90. When pivoted together along the long dimension, the semi-cylinder portions 80 form a hollow tube with a central passage 85, as shown in FIG. 11. This design advantageously permits the central passage 85 of the hinge connecting rod 75 to receive a plurality of electrical cables 35 prior to the semi-cylinder portions 80 being pivoted together to form the completed hinge connecting rod 785. In FIG. 10 is shown an example cable harness assembly 110 comprising a plurality of electrical conducting wires 35 bound together with cable fastening ties 100 and installed within an open hinge connecting rod 75. In an implementation, the cables 35 may be drawn through flexible grommets 105. The grommets 105 aid in protecting the wires from snarling and abrasion as they pass from the hinge assembly into the case interior. The grommets 105 can engage case side wall openings 95 by simply pressing the grommet into suitably molded flanges on the case housing side wall 55.

After the cable harness assembly is in place, the opposing members of the hinge connecting rod 75 can be pivoted together in order to complete the hinge connecting rod assembly 115 (see FIG. 11). As with the hinge segments, the complementary portions of the hinge connecting rod 75 may include means for openably securing the two halves together, thereby permitting maintenance of any electrical conductors residing therein. In FIG. 10 is shown an example implementation of fasteners 54 for this purpose.

The completed hinge connecting rod assembly 115 can then be installed into the open hinge segments 17 as depicted in FIG. 12, in order to stabilize the several hinge segments in a common axis and connect the corresponding members of the case housing. During this operation, the ends of the electrical wires 35 may be passed through corresponding openings in the hinge segments and case housing and into the interior of the case as shown in FIGS. 1-2, 12. Suitable grommets or fittings may be used to protect and hold the wires in place at these openings and to seal the interior of the hinge from moisture and debris. Finally, the hinge connecting rod is secured in place by pivoting the opposing halves 50 of the hinge segments together (see FIGS. 8A and 8B). Appropriate sealing closures or caps may be fitted to the terminal ends of the hinge assembly body to prevent water and debris from entering the hinge assembly interior (see FIG. 2).

It will be recognized that the connecting rod 75 behaves independently of the hinge segments 17; the hinge segments 17 rotate about the hinge rod 75 when the case housing members are opened and closed, while the hinge rod 75 advantageously remains substantially stationary during this action. This feature precludes the electrical wires enclosed within the hinge assembly from unnecessary twisting and bending when the case is opened and closed. In an implementation, the hinge rod may be made of a suitable material, such as polyolefin elastomers or include a Teflon coating, which reduces friction and allows the hinge segments to rotate smoothly and freely around it without requiring additional lubrication. In another implementation, the exterior side wall of the hinge connecting rod, or the interior side wall of the hinge segment may include one or more load-bearing ridges or surfaces for the hinge segments to rotate upon, thereby facilitating motion of the hinge segments. In other implementations, the hinge connecting rod may assume a different length, relative to the hinge assembly, than that exhibited in the drawing figures herein.

In FIG. 14 is shown a flow diagram representation of an example implementation of a hinge assembly process, in accordance with the inventive aspect described herein. Modifications to the process as presented may be contemplated without departing from the scope of the present disclosure.

From the foregoing description it will be appreciated that the various implementations disclosed herein provide a hinge assembly that is simple in design with a minimum of separate parts, inexpensively manufactured, and readily assembled. Further, the inventive aspects include a hinge assembly specially adapted to enclose and convey electrical conductors, such as cables, from one half of a carrying case to the other, while protecting the conductors from damage.

While various implementations have been described above, it should be understood that they have been presented by way of example only, and not limitation. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the implementations.
